Wind Turbine Blades
from Models by Dave
These Blades measure 15 3/8" long which is 111.6' in HO Scale. They are made of Cast Resin and need to be finish sanded and painted.
Here is one of the blades sitting on a Walthers 89' Flatcar. Plenty of overhang to make it look great with an idler flat. The Cradles that these blade sit in look fairly easy to build out of styrene.
Here is a Youtube Video of these blades set up on HO Scale Spine Cars:
Would also make a really neat Tractor Trailer load.
